A CORPORATION 0F MICHIGAN COWL VENTILATOR Application filed May 28,

This invention relates to cowl ventilators for automobiles and has forits general object the provision o f a cowl ventilator operatingmechanism which may be readily and conveniently operated to open orclose the ventilator and which will act automaticaly to hold the partsrmly in either the open or the closed position.

The more particular objects of the invention, together with meanswhereby the latter may be carried into effect, will be more clearlyunderstood from the following description of a preferred embodimentthereof illustrated in the accompanying drawings; in which,

Fig. 1 is a perspective view of a portion of an automobile bodyembodying the cowl ventilator of the invention;

Fig. 2 is a perspective view of the ventilator as seen from the interiorof the body; and

Figs. 3 and 4 are sectional detail views taken through the ventilatorwhen it is closed and opened respectively.

Before explaining in detail the present invention, and the method ormode of operation embodied therein, it is to be understood that theinvention is not limited in its application to the details ofconstruction and arrangements of parts illustrated in the accompanyingdrawings, since the invention is capableof other embodiments and ofbeing practised or carried out in various ways. Also it is to beunderstood that the phraseology or terminology employed herein is forthe purpose of description and not of limitation, and it is not intendedto limit the invention beyond the terms of the Several claims heretoappended or the requirements of the prior art.

As illustrated in the drawings, the cowl ventilator is embodied in anautomobile body comprising sill members 10 reenforced by cross members11. Suitable front pillarsv 12 are mounted upon the sill members and areconnected at their upper ends by a header 13 and below their upper endsby a belt panel 14, the windshield opening being` defined by the pillars12 and the header and belt panel. A cowl 15 is provided with an 1929.Serial No. 366,722.

opening 16 and is secured at its rear edge to the pillars 12 and beltpanel 14, the forward edge of the cowl being secured to the Iedge of adash 17.

The cowl opening 16 is surrounded by a suitable frame 19 of Z-shapedcross section which is secured to the interior surface of the cowl inanysuitablemanner as by rivets 21 so as to bring its opening 2O directlybelow the cowl opening 16. The cowl opening l16 is closed by a suitableventilator or closure having a cover or top portion 22 conforming to theform of the cowl. Apan-shaped frame 24 is secured at its forward edgeinany suitable manner to the under surface of the cover 22 and is providedwith side projections 25 which are also suitably secured to the undersurface of the cover 22. The frame 24 is provided at its rear end with aprojection 26 extending rearwardly and upwardly, the end of which isshaped to form a hinge member 27 cooperating with a hinge member 28depending from the -frame 19.

each ofl which a stud or bolt 39 is secured,V

each of which is adapted to project into a slot 40 in one of thelinlrs31. The bar 35 is formed near its center with a depending yoke 41within which one end of a hand operating lrod 42 is pivotally secured,the

other end of the rod 42 extending through a suitable opening or sleeveV(not shown) in the instrument board so that it may be easily accessibleto the driver. If desired, a foot `lever 43 may be secured to theventilator.

`As illustrated the lever 43 is secured by rivets 45 to the projection26 so as-to extend downwardly a considerably distance from theventilator.

The ventilator may be operated by the driver to open by pushing or toclose by pulling uponthe' rod 42 or similarly by moving the lever 43with the foot. In

center (as shown by the line lL -an in'Figs:

3and 4) the spring 32 acts to complete the movement and maintain theventilator in 'Y either an open or closed position depending upon thedirection of movement of the rod` 42 or lever 43. Theclosed'positionoi:` the ventilator, shown in Figs. 2 and 3, isdeterminedby engagement of the margin-al `edge of vthe coverf22 ,withthe. lower flange ofthe frame 19 or` preferably, with a suitable packingstrip 46 carried thereby, the Vsprings 32 yat this time acting toprcsssaid edge firmly against said flangeror packing strip so as to` preventrattling and excludev air, dust and rain., The lugs V are formed attheir lower ends with outwardly turned .ears 47 constituting stopswhich, when thel ventilator is openedareengaged by the links 3.1 tolimitthe opening movementand determinethe fully opened position, shownin Figs. 1 and 4,'the'isprings 32 at this time so acting to hold saidVlinks closely against' said stopsand again preventing rattling.
